Polyethylene glycol 6000 an shirya ta hanyar polymerization na ruwa ethylene glycol a babban zazzabi, matsin lamba ko ƙarancin ƙarfi.
Polyethylene glycol 6000 (PEG-6000) Sunan Ingilishi: macrogol 6000-992 wannan samfurin shine cakuda ethylene oxide da polycondensation na ruwa, tsarin kwayoyin shine ho (CH2CH2O) NH, inda n yake wakiltar matsakaicin adadin oxyvinyls.
hali
Wannan samfurin fararen mai yanƙane ne mai ƙwanƙolin haske ko ƙura mai ƙamshi, mai ɗanɗano mai ƙanshi. Samfurin yana narkewa cikin ruwa ko ethanol, amma ba za'a iya narkewa a cikin ether ba. Matsayin daskarewa na wannan samfurin (Shafi VI d) shine 53 ~ 58 ℃. Danko ya dauki 25.0g na wannan samfurin, saka shi a cikin kwalbar auna 100ml, kara ruwa ya narke ya narkar da sikelin, girgiza sosai, yi amfani da Pinker viscometer mai dauke da diamita ciki na 1.0mm don yanke hukunci bisa doka (Shafi VI g hanyar 1 ). Maganin kinematic a 40 ℃ shine 10.5-16.5mm <2> / s.

Tsaro
Ba shi da ɗan damuwa ga fata da idanu, kuma yana da wahala a shanye shi ta hanyar maganan ciki bayan gudanar da magana, kuma yawan guba yana da ƙasa ƙwarai. Allurar 5% (taro) mai ruwa-ruwa na polyethylene oxide a idanun zomaye ya haifar da ƙananan ƙonewa. PEO ba shi da tasiri kaɗan akan mutuwar kifi, kaguwa, Anemone, jatan lande ko algae. Feshin ta da kuma maganan ruwa mai ƙarancin mai guba, kuma amintacce ne amfani da shi. Hukumar Abinci da Magunguna ta Amurka (FDA) ta amince da amfani da sinadarin polyethylene oxide na ruwa mai narkewa don keɓaɓɓun kayan abinci da na giya kai tsaye.

dubawa
Matsakaicin nauyin kwayoyin wannan samfurin yana kusan 12.5g, wanda aka auna shi daidai. Sanya shi a cikin kwalbar mai taya 250ml tare da abin tsayawa, ƙara 25ml pyridine, zafafa shi ta narke, kuma sanyaya shi. Dangane da hanyar polyethylene glycol 400, farawa daga “maganin pyridine da aka ƙara tare da phthalic anhydride daidai”, matsakaicin nauyin kwayar halitta ya zama 5400-7800. Za a bincika acidity, tsabta da launi na maganin, da saura akan ƙonewa gwargwadon hanyar da aka ƙayyade a polyethylene glycol 400.
